【Example】

 An embodiment of a vehicular lamp according to the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 20 denotes a resin housing having a lens 21 provided in a front opening, and a rear wall 22 of the housing 20 has a cylindrical portion 24 having a rear opening 23 formed therein. . An annular support wall 25 extending rearward is provided around the cylindrical portion 24. As shown in FIG. 3, the support wall 25 is provided with a protrusion 26 protruding outward from the tip end portion thereof.

On the other hand, a resin reflector 31 having a valve 30 mounted therein is tiltably arranged in the housing 20, and a rear portion 32 of the reflector 31 is located in a rear opening 23. Then, the reflector 31 is tilted as shown by a broken line (see FIG. 1) by an optical axis adjusting mechanism (not shown).

A gap formed between the rear portion 32 of the reflector 31 and the tubular portion 24 of the housing 20 is sealed by an annular rubber cover 40 to prevent water from entering.

As shown in FIG. 3, the rubber cover 40 has an outer tubular portion 43 formed on the outer periphery of a flexible portion 42 provided on the outer periphery of the inner tubular portion 41. A mounting portion 32 a formed on the rear portion 32 of the reflector 31 is fitted into the inner cylindrical portion 41 of the rubber cover 40. Then, the cap 45 is put on the mounting portion 32a together with the inner cylindrical portion 41, and the inner cylindrical portion 41 is fixed to the mounting portion 32a. The cap 45 is fixed to the rear portion 32 of the reflector 31 with a screw N.

The outer cylindrical portion 43 of the rubber cover 40 is fitted to the outer periphery of the cylindrical portion 24 provided on the rear wall 22 of the housing 20, and the outer peripheral portion 42 a of the flexible portion 42 is fixed to the cylindrical portion 24 by the mounting ring 46. Has been done.

As shown in FIGS. 4 and 5, the mounting ring 46 has a leg portion 46b continuously formed in an annular shape at the outer peripheral end of a flat plate-shaped ring portion 46a, and a claw 46c is formed inside the leg portion 46b. The claws 46c are raised and provided at predetermined intervals. The claw 46c has an elastic force so that the tip end portion 46d of the claw 46c engages with the projection 26 of the support wall 25.

When the mounting ring 46 is mounted by pressing in the direction of the arrow P1 from the position indicated by the chain line in FIG. 3, the claw 46c bends outward due to its elastic force, and the mounting ring 46 is pushed in. When the mounting ring 46 is pushed into the position shown by the solid line in FIG. 3, the tip end portion 46d of the claw 46c engages with the projection 26 of the support wall 25. As a result, the attachment ring 46 can be reliably attached to the support wall 25 as shown by the solid line in FIG. By mounting the mounting ring 46, the outer tubular portion 43 of the rubber cover 40 is fixed to the tubular portion 24 of the housing 20, and the outer peripheral portion 42a of the rubber cover 40 is attached to the end surface 24a of the tubular portion 24 by the ring portion 46a of the mounting ring 46. It will be pressed.

As described above, the attachment ring 46 can be attached only by pushing it in, and moreover, the tip end portion 46d of the claw 46c can be reliably engaged with the projection 26 even if the elastic force of the claw 46c is weakened. , The pushing force can be reduced and the mounting work can be simplified.

When the internal pressure in the direction of arrow P2 is applied to the ring portion 46a, the tip of the leg portion 46b bites into the housing 20 in the direction of arrow P3 by its reaction force, so that the attachment ring 46 is more firmly attached. Becomes

Further, since the attachment ring 46 is attached by engaging the claw 46c with the protrusion 26 of the support wall 25, the attachment ring 46 may be made of resin, and can be made inexpensive.
